As promised some initial findings from the converting of HDV footage from a HC1E and HC3 to HD-DVD. 1. Having converted 50Hz 1440x1080i footage to a 1920x1080i/60Hz MPEG2 file and dumping onto DVD-R, the Toshiba HD-E1 does not recognise the file and displays an error message. 2. Creating a HVDVD_TS folder using Ulead DVD Movie Factory 5 Plus and the 1920x1080i/60Hz MPEG2 file and burning to DVD-R is still not recognised. The player states DVD format is unrecognised. Very disappointing. I'm going to cehck I've done nothing incorrectly, but it would appear you can't create a mini HD-DVD on a DVD-R, even when using a supported file format.
